record player

a device for reproducing the sounds stored on a record, consisting of a turntable, usually electrically driven, that rotates the record at a fixed speed of 33, 45, or (esp formerly) 78 revolutions a minute. A stylus vibrates in accordance with undulations in the groove in the record: these vibrations are converted into electric currents, which, after amplification, are recreated in the form of sound by one or more loudspeakers See also monophonic quadraphonics stereophonic
